产品详情
Wishpower 20kV pin type composite insulator is widely used in 20kV overhead distribution networks. It is normally installed on crossarms or pole-mounted supports to fix conductors and prevent electrical leakage to the pole structure. Compared with traditional porcelain pin insulators, composite pin insulators offer better lightweight performance, improved pollution resistance, higher impact resistance, and easier installation.
Main advantages include:
High-temperature vulcanized silicone rubber housing for excellent hydrophobicity and anti-pollution performance.
High-strength epoxy fiberglass core rod for stable mechanical performance.
Hot-dip galvanized metal fittings for enhanced corrosion resistance.
Lightweight structure for easier transportation and installation.
Suitable for 20kV distribution lines, overhead networks, and demanding outdoor environments.
Core Features
Reliable Electrical Insulation
The 20kV pin type composite insulator provides stable insulation protection for medium-voltage distribution systems and helps reduce flashover and grounding risks.Excellent Pollution Flashover Resistance
Silicone rubber housing maintains good hydrophobicity, helping the insulator perform reliably in dusty, humid, coastal, and polluted environments.Lightweight and Easy to Install
The composite structure is lighter than porcelain insulators, reducing pole load and improving installation efficiency.Strong Impact and Breakage Resistance
Composite insulators are less likely to suffer brittle fracture during transportation, handling, and field installation.Long-Term Outdoor Durability
The product is designed with UV resistance, aging resistance, tracking resistance, and erosion resistance for long-term outdoor operation.
Product Structure
The 20kV pin type composite insulator usually consists of the following components:
Silicone Rubber Housing
Provides external insulation, creepage distance, weather resistance, and pollution flashover protection.Epoxy Fiberglass Core Rod
Acts as the main mechanical load-bearing component and ensures structural strength.Metal End Fittings
Usually made of hot-dip galvanized steel or customized fittings for mounting and connection.Interface Sealing System
Protects the connection area between the core rod and metal fittings to prevent moisture ingress.Shed Design
Optimized shed profile increases creepage distance and improves insulation performance under wet and polluted conditions.
